TWO NEW CRABS FROM THE EOCENE OF TEXAS 



By Mary J. Rathbun 



Associate in Zoology, United States National Museum 



The species here described come from the same general region in 

 Texas. The Raninid was taken in a core drill, Lane No. 1, depth 

 260 feet, by the Marland Oil Co., a part of the Thomas Jordan 

 Survey of land in Navarro County. The Lane farm is located about 

 4 miles north of Kerens and 8 or 10 miles west-southwest of Tool in 

 Henderson County. Until now the genus Notosceles was known, 

 from only one species, a Recent one. 



The Xanthid was collected by John E. Adams, Bureau of Eco- 

 nomic Geology, Austin, Tex., in the bed of Little Brazos Creek, 

 Brazos County, on both sides of the old Bryan and Brazos Valley 

 Railroad bridge. 



The type-specimens are in the United States National Museum.

 at the middle of its length, lateral spine in front of middle of antero- 

 lateral margin. Surface minutely punctate, punctae close together;: 

 except on the frontal and orbital regions where the surface is densely-

 ridge which passes obliquely forward to a point just behind the- 

 inner of the orbital fissures and then transversely behind the front ;:
